Understanding Slime Chemistry

Which molecule is the main component of Elmer's glue used in slime making?

• Polyvinyl acetate (PVAc)

• Sodium chloride

• Water (H2O)

• Carbon dioxide

What is the role of borate ions in the slime-making process?

• They evaporate the water

• They cross-link with PVAc molecules

• They change the color of the slime

• They dissolve the glue

What is the first step in the slime-making process?

• Adding borate ions

• Heating the mixture

• Mixing glue with water

• Adding food coloring

Why is slime considered a non-Newtonian fluid?

• It evaporates quickly

• It has both liquid and solid properties

• It is always liquid

• It is always solid

What happens to slime when stronger forces are applied?

• It hardens permanently

• It changes color

• It tears and then reconnects

• It becomes more liquid
